Joomla needs a way for users to easily visualize how modules will appear on various pages. Users could resize and drag all modules (while simultaneously viewing the content) in order to easily make changes, as in Artisteer.

Improve IN/OUTparameter passing between Joomla and external applications (which could be wraped into Joomla framework). Passing username, password, +other critical parameters would help integrate Joomla with hundreds of other SOAP apps.

Replace the current system used here at idea.joomla.org with a Joomla extension (e.g. a customized version of obSuggest).

That additionally to the UserVoice features:
- Allow people to down vote a feature.
- Report abuse.
- Report duplicates.
- Display the time a comment was submitted/modified.
- Integrate with the other Joomla.org sites (single-sign-on).

Currently the tag component offers a list of items tagged or a list of tags, but it would be helpful to have a blog display, with all the same features and options of a "category blog," for each tag when clicked.

User id of joomla 1.6 admin isn't 1 - it's 4X, and in joomla 1.5 it's 6X,
reset autoincrement of jos_users to make the default administrator id=1 in the default package which is available on the site for download.

Admin is full of lists view like, module manager, plugin manager. And we can sort these by clicking to column's heading. In my opinion it should use json grid so that this will not require page load and will save time

Possibility to link a contact to more than one category. Example: Employee, Management, Project team. In general, the idea of linking an item to more than one category could apply to other items also, such as articles for instance. This would for instance reduce the use of featured articles as this would jus be another category.

The core components and modules in Joomla should be more compatible with Google Webmaster Tools. For example, the core menu module should bee compatible with google's menu indexing capability, and sitemaps should be auto generated.
